arm64: dts: qcom: sdm630: fix gpu_speed_bin size
Historically sdm630.dtsi has used 1 byte length for the gpu_speed_bin
cell, although it spans two bytes (offset 5, size 7 bits). It was being
accepted by the kernel because before the commit 7a06ef751077 ("nvmem:
core: fix bit offsets of more than one byte") the kernel didn't have
length check. After this commit nvmem core rejects QFPROM on sdm630 /
sdm660, making GPU and USB unusable on those platforms.
Set the size of the gpu_speed_bin cell to 2 bytes, fixing the parsing
error. While we are at it, update the length to 8 bits as pointed out by
Alexey Minnekhanov.
Fixes: b190fb010664 ("arm64: dts: qcom: sdm630: Add sdm630 dts file")
